[0018] In the accompanying drawings, FIG. 1 is a side view
illustrating a skin care device using a radio frequency (RF) needle
according to an embodiment of the present disclosure. FIG. 2 is a
cross-sectional view illustrating a cartridge fixing portion of the
skin care device using the RF needle according to an embodiment of
the present disclosure. FIG. 3 is a front view illustrating the
cartridge fixing portion of the skin care device using the RF

is a view illustrating a state before an operation of the skin care
device using the RF needle according to an embodiment of the
present disclosure. FIG. 5 is a view illustrating a state after an
operation of the skin care device using the RF needle according to
an embodiment of the present disclosure.
[0019] As illustrated in FIGS. 1 to 5, the skin care device using
the RF needle according to an embodiment of the present disclosure
includes: a head portion with which the cartridge fixing portion
100, a needle cartridge 200, an elastic body 300, and a cap 400 are
assembled; a hand piece (not illustrated) to which the head portion
is coupled and capable of being grasped by a user; and a vacuum
pressure formation unit (not illustrated) configured to form a
vacuum pressure on the head portion.
[0020] The cartridge fixing portion 100 is provided with a skin
contact part 120 that is formed at a front side of the cartridge
fixing portion 100 and has a plurality of needle holes 123, and a
space is formed inside the cartridge fixing portion 100. A vacuum
suction port 150 communicated with the skin contact part 120 and
configured to generate a suction force is formed at a front outer
circumferential surface of the cartridge fixing portion 100, and an
opening portion is formed at a rear side of the cartridge fixing
portion 100 and a coupling protrusion 160 is formed at the opening
portion.
[0021] The skin contact part 120 includes: a recessed portion 121
concavely formed at a front end portion of the cartridge fixing
portion 100; and a front surface plate 122 formed inside the
recessed portion 121 and having the plurality of needle holes
123.
[0022] A stepped portion 103 is formed between the front end
portion of the cartridge fixing portion 100 and the front surface
plate 122 so as to have a height difference therebetween.
[0023] Thus, as illustrated in FIG. 2, a longitudinal distance of
about 0.5 mm is formed between the front end portion of the
cartridge fixing portion 100 and the front surface plate 122, so
that a user's skin (S) may be close in contact with the front
surface plate 122 by a suction force that allows the skin (S) to be
inserted into the recessed portion 121.
[0024] The front surface plate 122 is placed by being concavely
recessed from an outer circumferential edge surrounding thereof so
that an outer circumferential groove 124 is formed, and a lower
surface of the outer circumferential groove 124 and an inner side
surface of the recessed portion 121 of the cartridge fixing portion
100 is connected to each other so as to be sealed.
[0025] Therefore, the outer circumferential groove 124 is formed in
a ditch shape that is formed along the outer circumferential edge
of the front surface plate 122, a hole 125 is formed on a portion
of the outer circumferential groove 124, and the hole 125 is
configured to communicate with the vacuum suction port 150.
[0026] The needle cartridge 200 is disposed in the space of the
cartridge fixing portion 100, and is provided with a plurality of
needles 220 that is configured to be inserted into the plurality of
needle holes 123 of the skin contact part 120.
[0027] The elastic body 300 is coupled to an outer circumferential
surface of the needle cartridge 200 and configured to provide an
elastic force to the needle cartridge 200 by being inserted to the
space of the cartridge fixing portion 100, and a coil spring is
suitable for the elastic body 300.
[0028] In addition, the needle cartridge 200 has an annular
protrusion 240 that protrudes from a front end portion of the
needle cartridge 200, has the plurality of needles 220 inside the
annular protrusion 240, has a plurality of injection tubes 260 that
correspond to the plurality of needles 220, and a first end portion
of the elastic body 300 is coupled to and fixed to the annular
protrusion 240.
[0029] The cap 400 is inserted through the opening portion of the
cartridge fixing portion 100 and has a plurality of through holes
so as to allow the plurality of injection tubes 260 to be coupled
thereto, and the cap 400 is coupled to the inside of the cartridge
fixing portion 100 and is configured to seal same so as to allow
the needle cartridge 200 and the elastic body 300 to be
accommodated inside the cartridge fixing portion 100.
[0030] The vacuum pressure formation unit (not illustrated)
includes a vacuum pump, and generates the suction force on the skin
contact part 120.
[0031] Therefore, the vacuum pressure is formed at the cartridge
fixing portion 100 and the skin is in close contact with the front
surface of the skin contact part 120 by the vacuum pressure that
pulls the skin, whereby the needles 220 may be inserted into the
skin that is in close contact with the skin contact part 120.
[0032] Meanwhile, according to an embodiment of the present
disclosure, the needles 220 have surfaces thereof coated with gold.
Using gold to coat the needles, that is, using a needle that is not
insulated by being gold-plated is advantageous over using a
stainless steel needle that is insulated.
[0033] By emitting a radio frequency (RF) through the needles 220
that are gold-plated, the RF is inserted to the maximum penetration
depth, and when an impedance of a dermis is lower than an impedance
of an epidermis, the RF may flow through the dermis without a
coagulation phenomenon of the epidermis.
[0034] Therefore, the needles 220 that are gold-plated provide
better RF conductivity than that of stainless steel needles, so
that a treatment effect may be improved.
[0035] In addition, an emission of the RF through the entire of the
needles 220 that are gold-plated provides a coagulation effect that
alleviates a microhemorrhage.
[0036] In other words, a gold-plated needle provides better RF
conductivity than a stainless steel needle, so that a treatment
effect may be improved.
[0037] Hereinafter, an operation of the present embodiment will be
described.
[0038] As illustrated in FIG. 4, in a state of the vacuum pressure
formation unit (not illustrated) being turned off, the needles 220
are in a state before being inserted into the skin.
[0039] Since a curved portion of the skin is spaced apart from the
skin contact part 120, some of the needles are spaced apart from
the skin or have a shallower insertion depth than that of other
needles.
[0040] Therefore, the RF may not be uniformly reached to the
dermis, which may cause a reduction of effectiveness in the
treatment.
[0041] Next, as illustrated in FIG. 5, when the vacuum pressure
formation unit is turned on, the vacuum suction force is formed at
the recessed portion 121 of the skin contact part 120, so that the
skin is pulled and inserted into the recessed portion 121 and is
close in contact with the front surface plate 122. Therefore, since
the skin is inserted into the skin contact part 120, there is no
portion that is spaced apart from the front surface plate 122.
[0042] In this manner, the needle cartridge 200 moves forward and
the needles 220 are drawn through the needle holes 123 with a state
of the skin being in close contact with the front surface plate
122, so that the needles 220 may be inserted into the skin with a
predetermined depth, thereby stably ensuring the effect of the
treatment.
[0043] Although preferred embodiments of the present disclosure
have been described for illustrative purposes, those skilled in the
art will appreciate that various modifications, additions are
possible, without departing from the scope and spirit of the
present disclosure as disclosed in the accompanying claims, and it
should be understood that the various modifications, additions are
included within the scope of the accompanying claims.
